 :::danger Keep the fee recipient set to Smooth's address!
-It is extremely important that you keep the fee recipient of your validator set to Smooth's address (`0xAdFb8D27671F14f297eE94135e266aAFf8752e35`) as long as it is subscribed to Smooth. If, at any point, you change the fee recipient of your validator and propose a block without unsubscribing first, you will be banned from Smooth and will not be able to participate in it again.
